Abstract

The invention provides a nickel hydrogenation catalyst for a C5 petroleum resin. The catalyst comprises an alumina-titanium oxide compounded carrier and an active component of nickel oxide and an auxiliary agent of magnesium oxide or copper oxide which are loaded on the compounded carrier. The weight ratio of alumina to titanium oxide in the compounded carrier is 3 : 1 -6 : 1; the content of nickel oxide is 12-18% based on the weight of the catalyst; and the content of magnesium oxide or copper oxide is 3-7% based on the weight of the catalyst. The catalyst has good low temperature hydrogenation activity and good stability in the hydrogenation process of the C5 petroleum resin. The invention also provides a preparation method of the catalyst and an application of the catalyst in catalytic hydrogenation of the C5 petroleum resin.

Description

technical field [0001] The present invention relates to a C 5 A petroleum resin hydrogenation catalyst and a preparation method thereof, in particular to a nickel-based hydrogenation catalyst and a preparation method thereof. Background technique [0002] With the continuous development of my country's petrochemical industry, the production capacity of ethylene is also increasing year by year. C 5 Petroleum resin is a by-product of ethylene plant C 5 The distillate is the main raw material, and it is a solid or viscous polymer with a relatively low molecular weight that is polymerized in the presence of a catalyst, and its average relative molecular weight is generally between 1000-3000. The resin is cheap and has excellent properties such as acid resistance, alkali resistance and aging resistance, so it is widely used in adhesive tapes, hot melt adhesives, road coatings, inks and rubbers. Existing C 5 Petroleum resin is generally reddish-brown, with a softening point o...
